nah, its a great combo just not before your ready to go to sleep
i took ~450 mg of pure dxm at about 4 pm, smoked a joint (est 1.3g) 30 minutes later, took 3mg of xanax directly after and then i smoked again (2g blunt, spliffed with grape swisher tobacco. i took 2mg more of xanax and drank a 6 pack, i was up until 5 am, laid inbed at 2:30-3 ans was sitting there trembling and rocking until about 4 when i icould finally control myself and then fell asleep sometime around there. woke up at noon(ish) feeling like i did not dream or anything yet i woke up more refreshed than i have ever been
Shit son i've never done that many things at once, i've done DXM and weed and weed and xanax and obv all alone but not combined into such a large amount. But yeah i bet being that high when you woke up the DXM basically pushed the reset button on your brain which is why you feel so refreshed. Just be careful tho mate cause i used DXM daily a couple years ago and gained a psychological dependency, you should be fine as long as you don't take it more than about once a week. Either way tho man that DXM gets you into that state of awareness (that i like) and there's no way out until its over.
Happy tripping!
